 V 7. Crabro ariel. (Tab. IX. figg. 7, $ ; 7 a, J organ ; 7 £, c? antenna.) 



Niger, nitidus, linea pronoti, metanoto, abdominis lineis 3 tibiisque ex parte flavis ; alis fuscis. $ et c? . 

 Long, fere 10 millim. 



Edb. Mexico, Ciudad in Durango 8100 feet (Forrer), Omilteme in Guerrero 8000 feet 

 (II. H. Smith). 



Head above densely covered with long fuscous hair, the orbits and clypeus with 

 silvery pubescence, closely and somewhat strongly punctured. Eyes behind not 

 reaching to the middle of the head. Ocelli in a curve, separated from each other by a 

 much less distance than they are from the eyes. Antennal groove shining, aciculate. 

 Thorax closely rugosely punctured ; scutellum longitudinally rugose. Median segment 

 rugose, furrowed down the centre, the basal area hardly defined. Pronotum almost 

 transverse above ; the edges obliquely truncate. Pleurae and median segment bearing 

 longish white, the mesonotum fuscous, hair. Abdomen shining, aciculate. Pygidial 

 area strongly and closely punctured at the base ; the narrowed apex with the punctures 

 large and widely separated. The transverse cubital nervure received almost in the 

 middle of the radial cellule. The scape of the antennae, an interrupted line on the 

 pronotum, the tubercles, metanotum, a mark on either side of the basal segment, a 

 complete line on the second segment, the fourth and fifth segments, the four anterior 

 tibiae in front, the greater part of the hinder tibiae, the spurs, and the metatarsus 

 (except at the apex), clear citron-yellow ; tegulae piceous. The long spur on the hind 

 tibia? reaching beyond the middle of the metatarsus. 



This species is much more shining than any of its allies. 



v 8. Crabro hector. (Tab. IX. fig. 8, $ .) 



Niger, crebre punctatus, clypeo aureo-piloso ; metanoto abdominisque maculis 6 flavis ; alis fumato-hyalinis. $ . 

 Long. 11-12 millim. 



Hab. Mexico, Amula in Guerrero 6000 feet (H. H. Smith). 



Front and vertex with a close finely rugose punctuation ; the front broadly depressed ; 

 frontal furrow shining, of nearly equal width throughout, a furrow running to it from 

 the ocelli. The ocelli almost in a triangle ; the hinder ones separated from each other 

 by about the length of the fourth antennal joint, and from the eyes by a somewhat less 

 distance than the length of the third— by a greater distance than they are from each 

 other. Cheeks normal. Clypeus sharply keeled in the centre. The third antennal 

 joint is nearly as long as the fourth and fifth joints united, but distinctly thinner than 

 they are, and dilated at the apex. Collar transverse, the edges obliquely rounded, 

 furrowed in the centre. Mesonotum finely rugosely- punctured, and bearing three 

 longitudinal keels in the centre at the base. Scutellum longitudinally rugose, as long 

 as the second tarsal joint. Median segment at the base with large irregular punctures ; 

 with some stout striations in the centre on either side of the narrow, not very distinctly
